Progression
percentage
Originally posted on r/Fitness by user nSuns. Five days, alternating heavy/volume waves, with auto-progression based on AMRAP performance.
Suits intermediates who can recover from 5 sessions a week and want fast linear-style gains for 8-16 weeks.
RepRoute manages the AMRAP-based progression automatically and triggers a deload when 3+ AMRAP sets fail.
Pros
- • Very high volume → strong hypertrophy response
- • Rapid strength gains for intermediate lifters
- • Built-in weekly progression
Trade-offs
- • 6 days/week is demanding on recovery
- • Not suitable for beginners
- • High injury risk if sleep/nutrition aren't solid

Common questions
Most lifters run nSuns for 8-16 weeks before recovery limits force a transition. RepRoute suggests 5/3/1 BBB as a deload-friendly successor.
Yes — the Pro+ Smart layer can compress nSuns into a 4-day rotation if your weekly schedule doesn't fit 5.
No. Stick with GZCLP or StrongLifts until linear progression stalls, then consider nSuns.
